While working as a teacher in the DWMA, Tokunaga wears a black suit with a white collared shirt and a long black necktie. He has black shoulder-length wavy hair, that's neatly brushed back and out of his face, He also wears thick framed rectangular glasses over his bright yellow eyes which have no pupils.

When he's not in the DWMA his appearance changes dramatically. He's no longer wearing the suit jacket and the tie is loosened as well as his shirt, which is untucked and the top button is undone, exposing his neck a bit more. He is no longer wearing his glasses and his wavy hair is messy and looks curlier.
